Disconne Question
. Wet trees can also absorb radio waves better then dry ones. Trees have vascular systems so are "wet" all the time. Dry trees are dead trees, http://www.biology4kids.com/files/pl...lemphloem.html |

The difference between summer and winter on 2m and up is certainly noticeable and measurable here in Minnesota. tom K0TAR |

I was responding to "wet" versus "dead". The difference between summer and winter on 2m and up is certainly noticeable and measurable here in Minnesota. And the difference is attributed to what? Very very simple physics. tom K0TAR |

What planet do you live on? Interference had nothing to do with the discussion. Conduction of objects in the local environment has everything to do with reception. tom K0TAR |

Your license is new in August this year. And tied to a canceled callsign in 1999. Odd history. tom K0TAR |
